Be it known' that I, LIONEL dent of Libertyville, County of Lake, and

State of Illinois, have invented certain new' and useful Improvements in TeabCups, of

Whieh'the' following is a specification; and

which are illustrated in the ,aceompanfying drawings, forming a part thereof.

The invention relates use in connection With milking machines; its objeet'being to simplify and generally improve upon the construction 'of dev'ices ofthis character. The invention Consists of: an outer shell preferably ela5tictube with'mthe casing.and

' having 1ts:upper end inturned t0 forin a sealing flap for' inclosing the cows teattbe fold -of the tube overlabping thet0 teat cups for:

Boni, :1 subject of the King of Great Britain, and res1a casing shoulder and preferably inclosing. a r1gid r1ng,and' an annular' nut m threadcd engagement with the end of the .casing and binding the foldof the tube to the shoulder. Means are provided' for scuring the lower end of the tube within the casing, and for the attachmenb of a suction tube, but this latter cature is nthout novelty.

In the drawings iilustrating the invnt1on, Figure 1 15 a perspective 0 one form 0J tube d1sconnected from the casmg; F 1g.

The invention relates to improvements in the tout cup forming the subject of Lettors Patent N0.'1,144,346,; issued to me J1'1ne r The de'vice comprises an Outcr shell. or.

casing 10 of rigid material, and preferably of metal, within which is incloSed a flexible and preferably elastic tube '11, having its ends in sealed engagement with the casing, the lower end of the tube inclosing a nippl'e 12 to which a suction and milk-conveying tube may be attached, and the casing being also;provided With a nipPle 13 to whichia :suct1ontube mayv beattached; An anr 1ular nut 14 is in threaded engagementwith the pper end of the Gasing 10,'its instanding flange binding an Oi1twardly pr0jeting fold ,of the tube against an instanding annular shoulderl5 of the calsing. The tube 11 may be noxfmally of.uniform diameter froni end to end and adtptedto freely enter the casing past'th'e shoulder 15. A rigidring 416 -.is-'inserted Within'the tube for the purpose of expanding it over the shoulder 15, and the end of the tube isthen turned inWardtd form' a depending conical shaped annular flap 17. The fol d {18 'of the tube extends over the shoulder 15, and, thenut being apthe casing-sholder. Ireferably, however,

form an'instanding annular flap 20. The ring 16 being inserted into .the tube and fored to the base ofthis flap, expands the tube to the fOrm' as shown in Fig. 4." {'In either form the tube is rndered moredurable and pliable, and amore perfectseal withthe casingat its upper end is secured.

The parts. are easily assenibled and dis .plied', Compresses itupon the ring and pon as shown in Fig.3, the tube 19 is. molded to connected for Cleansing, -in either frmflofb construction the flap bein'g easily outturned whehthe tube is freed from the casing, leaving its inner surface s'mooth and without creases; 1
